Overview

Bandai Meito Resort Bonari no Mori is a hot spring resort in Nakanosawa Onsen, within Bandai-Asahi National Park in Fukushima. You stay surrounded by forest, mountain air, and the strong hot spring culture of the Numajiri Motoyu and Nakanosawa source area. The setting works well when you want a quiet highland stay with milky onsen water, Aizu food, and easy access to Inawashiro, Mt. Bandai, and Aizu sightseeing.

The hot spring source is one of the main reasons to stay here. Numajiri Motoyu and Nakanosawa Onsen have a single-source flow of 13,400 liters per minute, one of Japan’s highest hot spring outputs. You can enjoy this water in large public baths, open-air baths, saunas, and a private reservable cypress bath.

Accommodation

You can choose from rooms in J-style Villa and The Main building. J-style Villa offers wider rooms with a villa-like feeling, while The Main gives you more casual Japanese and Western-style options for a simple hot spring stay. Every room has Wi-Fi, and room windows look toward the surrounding natural scenery of Bandai-Asahi National Park.

The standout room is Forest Suite 101, a renewed 73㎡ suite with a living room, bedroom, Japanese room, and semi-open-air bath using hot spring source water. This is the best room choice when you want more space and private bathing without leaving your room.

J-style Villa also includes a 14.5-tatami Japanese-style bedroom with massage chair and bathroom, a 14.5-tatami Japanese-style bedroom, and a 14.5-tatami Japanese room. These rooms give you more space than the standard rooms and suit you when you want a relaxed stay with forest views.

The Main building includes a 20-tatami Japanese force room with four beds, a 10-tatami Japanese room, an 8-tatami Western-style room, and an 8-tatami Japanese-style bedroom with beds. These rooms are a good match when you want a straightforward base for onsen, meals, and sightseeing.

Room equipment includes TV, warm-water washing toilet, safe, tea set, refrigerator, hair dryer, and individual air conditioning. Amenities include toothbrush set, towels, bath towels, hand towels, razor, yukata, and slippers.

Dining

Dinner highlights Aizu flavors through the Aizu BUKE Wazen, a seasonal Japanese meal inspired by Aizu’s samurai food culture. You can enjoy dishes such as Aizu-style appetizers, kozuyu local soup, Date chicken kamameshi, and a main dish that changes depending on your plan.

Main dish choices may include Fukushima beef A4 loin suki-shabu, black wagyu and Hayama Kogen pork suki-shabu, Fukushima beef A4 loin shabu-shabu, domestic black wagyu shabu-shabu, or Hayama Kogen pork shabu-shabu. Extra dishes can include salt-grilled ayu and a three-cut tasting of Aizu horse sashimi.

Aizu is known for sake, and you can pair your meal with local sake made with regional rice, water, and brewing traditions. Breakfast is usually buffet style, with seasonal vegetables, Aizu Koshihikari rice, and local dishes. On some days, breakfast may change to a Japanese set meal.

If you have food allergies, please contact the property in advance. Allergy support is handled through a communication sheet, and requests should be made at least 5 days before your stay.

Onsen and Wellness

The baths use water from Numajiri Motoyu and Nakanosawa Onsen. The spring quality is acidic, sulfur-containing calcium-aluminum sulfate-chloride spring water, with pH 2.1 and a source temperature of 68.3°C. Listed indications include neuralgia, muscle pain, joint pain, motor paralysis, chronic digestive issues, sensitivity to cold, fatigue recovery, chronic skin disease, and chronic women’s health concerns.

You can soak in Kawasemi no Yu, a rock-style open-air bath facing forest and a small stream, or Yamasemi no Yu, an open-air bath with ancient cypress on the tub edge. Both open-air baths operate from afternoon to late evening, with gender switching after the late-night cleaning period.

The large indoor baths include Kawasemi no Yu, filled with source-flowing hot spring water, and Yamasemi no Yu, where you can enjoy the milky cloudy water that Nakanosawa Onsen is known for. Each large public bath also has a dry sauna.

You can also reserve the private cypress bath on the day of use. It uses source-flowing Nakanosawa Onsen water and has a barrier-free layout with no steps from the entrance to the tub area, plus a handrail near the bath. This is the best choice when you want a quieter soak or easier access.

Guests with Tattoos

The private cypress bath gives you the most private bathing option on site. You cannot use the public onsen with tattoos.
